Gastrointestinal stromal tumor in ileal neobladder

Abstract  Gastrointestinal stromal tumor (GIST) is a recently described mesenchymal tumor that can develop in any portion of the gastrointestinal tract. The occurrence of a GIST in the urinary tract is rare, but GIST can present as tumor of the urinary tract or invade the urinary tract. This is the first reported case of GIST in the ileal neobladder, which presented as a submucosal tumor. The patient underwent an open exploration and partial resection of the neobladder pouch.     

Effects of erythromycin on the propulsive motility of upper gastrointestinal tract in rats

The differences between the postprandial mixing or propulsion and the interdigestive motility of the gastrointestinal (GI) tract are already known. Earlier studies showed dose-dependent differences in the effects of erythromycin on interdigestive motility. The various GI side-effects (vomiting, diarrhoea) also suggest that there are different effects of erythromycin on the GI motility. The aim of our study was to examine postprandially the propulsive effects of different doses of erythromycin on the movement of intraluminal contents in the upper GI tract of the rat. The animals were fasted for 24 h before the experiments but water was given freely. The rats received 1.5 ml 1.5% methylcellulose painted with 0.05% phenol-red intragastrically (test solution). Erythromycin(E. lactobionate) was given intravenously at doses of 0.05, 0.1, 0.25, 0.5, 1.0 and 5.0 mg/kg 15 min before the administration of a test solution. The animals were sacrificed 20,60 and 120 min after administration of methylcellulose, when the distance between the front of the painted intraluminal contents and the pylorus was measured and expressed as a percentage of the total length of small intestine. The phenol-red content in the stomach and small intestine was measured spectrophotometrically and the gastric emptying was calculated from the ratio of the measured total and intestinal phenol-red content. Our results showed that the small doses of erythromycin (0.1 and 0.25 mg/kg) accelerated gastric emptying after 20 min but did not change significantly the propulsive motility of upper small intestine; however, large doses of erythromycin (1.0 and 5.0 mg/kg) decreased gastric emptying and upper GI motility after 20 and 60 min. In summary, the prokinetic action of small doses of erythromycin was demonstrated, but its effecttime on GI motility is short and the ratio of the stimulating and inhibitory doses is 1:10. This paper was presented at the Section of IUPHAR GI Pharmacology Symposium on ’Biochemical pharmacology as an approach to gastrointestinal disorders (basic science to clinical perspectives)‘, October 12-14, 1995, Pécs, Hungary.

Angiodysplasia as the cause of massive lower gastrointestinal hemorrhage in a young adult

PURPOSE: This study was undertaken to clarify the importance of bleeding vascular ectasia of the colon as the etiology of massive lower gastrointestinal hemorrhage in patients 40 years of age or younger. METHODS: An otherwise healthy 21-year-old male was admitted to a tertiary medical center with massive lower gastrointestinal hemorrhage. Technetium-labeled red blood cell scan, selective visceral angiography, and colonoscopy identified the source of bleeding as vascular abnormality of the descending colon. Segmental colonic resection was performed. RESULTS: Histologic review of the specimen demonstrated a vascular ectasia. The patient recovered uneventfully and has had no further stigmata of hemorrhage. A review of the literature was undertaken to make clear the significance of vascular ectasia as the source for massive colonic hemorrhage in the young adult. CONCLUSION: This is the first report that documents histologically a vascular ectasia as the source of massive lower gastrointestinal hemorrhage in an otherwise healthy patient less than 40 years of age. Vascular ectasia is an uncommon cause of lower gastrointestinal hemorrhage in the young adult.The Chief, Bureau of Medicine and Surgery, Navy Department, Washington, DC, Clinical Investigation Program sponsored this report #84-16-1968-532, as required by HSETCINST 6000.41A.

Fricke supraorbital flap for reconstruction of total lower eyelid defects

Summary Split or full thickness eyelid defects resulting from tumor destruction or surgical excision present a dilemma for plastic and reconstructive surgeons. Full thickness eyelid replacement requires composite grafting of the skin, together with tarsal support of its substitute and mucosa. The flap described by Fricke in 1829 was used for reconstruction of anterior lamella in six lower eyelid defects. In three of our cases chondromucosal grafts taken from nasal septum were utilized for posterior lamella repair. The results have been satisfactory from a functional and cosmetic standpoint.     

不同低浓度罗哌卡因低位硬膜外镇痛对运动神经阻滞的临床观察

目的 观察不同低浓度罗哌卡因（ropivacaine,Rop）低位硬膜外镇痛对运动神经的阻滞作用。探讨罗哌卡因低位硬膜外镇痛的最佳药物浓度。方法 随机选择我院67例下腹部择期手术患者，术后随机分为5个治疗组（A、B、C、D、E）和一个对照组（F），3h后硬膜外腔用药。前5组使用不同浓度罗哌卡因（A：0.1%;B:0.15%;C:0.2%;D:0.25%;E:0.3%），F组使用0.9%生理盐水。注药前后20分钟分别观察、记录以下项目：1.视觉模拟评分（Visual analogue scale,VAS）；2.阻滞区运动神经反射；3. 下肢指令运动。结果 不同低浓度罗哌卡因均有程度不同的术后镇痛作用。对运动神经的阻滞作用A、B、C三组与对照组无显著性差异（P＞0.05），而D、E两组有显著性差异（P＜0.05）。结论 选择浓度为0.2%的罗哌卡因低位硬膜外镇痛既可以有效地发挥术后镇痛作用，又最大程度地减少了对运动神经的阻滞作用，有利患者术后恢复。     

Chronic intestinal pseudo-obstruction: manifestations, natural history and management

Chronic intestinal pseudo-obstruction (CIPO) is a rare pathological condition characterized by a marked derangement of gut propulsive motility mimicking mechanical obstruction, in the absence of any lesion occluding the gut lumen. This disease is often associated with a disabling and potentially life-threatening complications and is still too often unrecognized even in referral centres. As a result, patients receive neither appropriate care nor recognition of their severe health condition. Medical and surgical therapies are often unsatisfactory and long-term outcome turns out to be poor in the vast majority of cases. This article focuses on the main clinical features, the management and long-term outcome of patients affected by CIPO, with particular emphasis on those aspects which remain a matter of debate.     

Multi-detector CT angiography for lower gastrointestinal bleeding: Can it select patients for endovascular intervention?

This is a retrospective review of the results at our institution of using multi-detector CT angiography (CTA) to localise lower gastrointestinal (GI) bleeding. We hypothesised that in our patient population: (i) CTA was unlikely to demonstrate bleeding in patients who were haemodynamically stable; (ii) in haemodynamically unstable patients in whom CTA was undertaken, the results could be used to select patients who would benefit from catheter angiography; and (iii) in haemodynamically unstable patients in whom CTA was undertaken, a subgroup of patients could be identified who would benefit from primary surgical treatment, avoiding invasive angiography completely. A retrospective review was conducted of the clinical records of all patients undergoing CTA for lower GI haemorrhage at our institution between 1 January 2005 and 30 June 2007. Out of the 20 patients examined, 10 had positive CTAs demonstrating the bleeding site. Nine were haemodynamically unstable at the time of the study. Four patients with positive CT angiograms were able to be treated directly with surgery and avoided invasive angiography. Ten patients had negative CTAs. Four of these were haemodynamically unstable, six haemodynamically stable. Only one required intervention to secure haemostasis, the rest stopped spontaneously. No haemodynamically stable patient who had a negative CTA required intervention. CTA is a useful non-invasive technique for localising the site of lower GI bleeding. In our patient population, in the absence of haemodynamic instability, the diagnostic yield of CTA was low and bleeding was likely to stop spontaneously. In haemodynamically unstable patients, a positive CTA allowed patients to be triaged to surgery or angiography, whereas there was a strong association between a negative CTA and spontaneous cessation of bleeding.     

子宫内膜萎缩疗法治疗青春期功血362例临床研究

目的：探讨子宫内膜萎缩疗法治疗青春期功血（DUB）的止血效果。方法：将362例平均分为观察组（采用炔诺酮、戊酸雌二醇联合疗法止血）和对照组（单用炔诺酮子宫内膜萎缩疗法止血），两组各181例，比较两组的止血效果。结果：观察组和对照组止血有效率分别为96．13％（174／181）和92．27％（167／181），两组比较差异无统计学意义（踟105）；观察组和对照组控制出血时间分别为（28．69±14．87）h和（29．72±15．34）h，两组比较差异无统计学意义（踟．05）。观察组和对照组的完全止血时间分别为（32．80±19．10）h和（47．30±18．60）h，两组比较差异有统计学意义（／9〈0．05）。观察组和对照组的住院天数平均为（6．10±2．80）d和（6．9±2．60）d，观察组住院时间短于对照组（P〈0．01）。结论：炔诺酮止血疗法和炔诺酮、戊酸雌二醇联合疗法治疗青春期功血效果均较好，但炔诺酮、戊酸雌二醇联合疗法治疗效果更佳。
